Application Augustl'l, 1950 ,-Seria l'N0';178,072

This invention has to do with pipe spacers and relates more particularly to a spacer for retaining a pipe in position spaced between contiguous rafters or other structural members in building construction.

It is an object of the invention to provide a pipe spacer which may be sold, shipped and stored in flattened and stacked condition and which may be easily formed into circular position around the pipe when placed in use.

It is also an object of the invention to provide a pipe spacer which is adjustable lengthwise or circumferentially so as to be fitted onto pipes of varying diameters.

A further object is to provide a pipe spacer which may be installed on the pipe after the pipe is installed in the structure.

Another object is to provide a pipe spacer which securely centers the pipe between two adjacent structural members and. which provides ample air space around the pipe.

Additional objects will appear as the following detailed description of a presently preferred embodiment of the invention proceeds, for which purpose I shall refer to the accompanying drawings, wherein:

Fig. 1 is a perspective of my pipe spacer device in flattened condition;

Fig. 2 is a side elevation showing the device in use for the purpose of spacing a pipe medially between two rafters;

Fig. 3 is an enlarged section taken on line 3-3 of Fig. 2; and

Fig. 4 is an enlarged fragmentary view.

In the drawings my spacer is generally denoted by the numeral 5 and is a stamping made from sheet metal to provide a rectangular strip having transverse corrugations 1 and 8. Each of the corrugations has, adjacent each side edge,

a longitudinally embossed reinforcing bead 9 which extends from one of the flattened high points Ill to the continguous like high point.

Each corrugation 1 has a web or strip I 5 struck out of the metal forming the corrugation and bent upwardly out of the plane of the corrugation into a somewhat arched position.

One end i6 is bent into position at right angles to the plane of the contiguous portion, and the latter portion is provided with parallel transverse slits IT. The portion 18 between the slits is bent LCIEQT'IS. (01. 248 65):

, 2:11- i each has its inner end secured to the strip 5 within one of the corrugations 8, as by a rivet 21. The opposite end portion of each strap is provided with nail receiving holes 28 to facilitate fastening the straps to a rafter R or other suitable structural member.

The spacer devices may be stacked one on the other with the webs I5 of a lower device fitting in the holes 30 of an upper device and with the intervening corrugations 8 in superimposed relation. The straps remain straight as shown in Fig. 1 until ready for use.

The devices are preferably made of a metal having suflicient pliability to allow them to be bent into circular form about a pipe in use, to allow the straps to be bent into the circular position shown in Fig. 2, and to allow the extreme outer end portion of the tongue 20 to be bent outwardly after being passed through the slits ll. The tongue is of suflicient length to enable considerable lengthwise adjustment of the device to fit pipes P of varying diameters.

The corrugations provide ample air circulation space above the pipe.

I claim:

1. A device comprising a pliant, transversely corrugated strip having a tongue-like extension at one end and a tongue-receiving slot at its other end, alternate corrugations of said strip having longitudinal, medial strips struck therefrom and bent out of the plane of the corrugations into arched position, said strip being adapted to be bent into circular shape around a pipe and retained in such shape.

2. A device for spacing a pipe between two structural members comprising a pliant transversely corrugated strip having a tongue-like extension at one end and a tongue-receiving slot at its other end, and a pair of strap members secured at one end to the strip at points spaced apart longitudinally thereof and extending laterally therefrom for attachment at their outer ends to said respective structural members, said strip being adapted to be bent into circular shape around a pipe and retained in such shape, and said corrugations having longitudinal embossed reinforcing beads adjacent and parallel to their side edges.

3. A device for spacing a pipe between two structural members comprising a pliant transversely corrugated strip having a tongue-like extension at one end and a tongue-receiving slot at its other end, and a pair of strap members secured at one end to the strip at points spaced apart longitudinally thereof and extending laterally therefrom for attachment at their outer ends to said respective structural members, said strip being adapted to be bent into circular shape around a pipe and retained in such shape, and said corrugations having longitudinal embossed reinforcing beads adjacent and parallel to their side edges and transverse fiat portions, between contiguous corrugations.

4. A device for spacing a pipe between two structural members comprising a pliant transversely corrugated strip having a tongue-like extension at one end and a tongue-receiving slot at its other end, and a pair of strap members secured at one end to the strip at points spaced apart longitudinally thereof and extending laterally therefrom for attachment at their outer ends to said respective structural members, said strip being adapted to be bent into circular shape around a pipe and retained in such shape, and alternate ones of said corrugations having longi- 4 tudinal medial strips struck therefrom and bent out o! the plane of the corrugations into arched position.
